The year without a summer, The Times, London, England, July 5, 1816

A Hamburgh paper contains the following extract of a private letter from Bordeaux, dated June 15: - “We really do not know here where we are. We sit with our doors and windows closed, and with fire burning on the hearth, as in the middle of winter. It is as cold as in October, and the sky is dark and rainy. Violent winds, accompanied with heavy rain and hail, rage round our country houses; the low grounds are under water; if we have one tolerably warm day, several cold and rainy ones are sure to follow. The oldest people in the country do not recollect such a summer.”

From Wikipedia:

The year 1816 is known as the Year Without a Summer (also the Poverty Year, the Summer that Never Was, Year There Was No Summer, and Eighteen Hundred and Froze to Death), because of severe climate abnormalities that caused average global temperatures to decrease by 0.4–0.7 °C (0.7–1.3 °F). This resulted in major food shortages across the Northern Hemisphere. Evidence suggests the anomaly was predominantly a volcanic winter event caused by the massive 1815 eruption of Mount Tambora in the Dutch East Indies (Indonesia), the largest eruption in at least 1,300 years after the extreme weather events of 535–536. The Earth had already been in a centuries-long period of global cooling that started in the 14th century. Known today as the Little Ice Age, it had already caused considerable agricultural distress in Europe. The Little Ice Age’s existing cooling was aggravated by the eruption of Tambora which occurred during its concluding decades.
